为了合理利用自然财富，必须清楚地认识正在我们眼前发生的景观变化。这些变化既是自然过程的结果，也是人类经济活动的结果。许多自然过程进行得如此缓慢，以至于在平原地区，近几个世纪以来具有实际意义的可能只是气候的世纪性波动及其相关现象。而人类的经济活动则相反，会引起地理环境迅速而深刻的变化。然而，人类对自然影响的许多方面尚未充分阐明，其活动的实际意义常常被低估甚至完全被忽视。\n本书试图揭示里海低地西北部粘土质半荒漠地区近两个世纪以来，在人类经济活动影响和湿润程度世纪性波动作用下，植被覆盖和动物界所发生的变化。其中特别关注作为经济活动主要方面的副产物过程，因为它们最常被忽略。书中不涉及各种经济活动的直接结果，也不涉及促成里海低地西北部景观人为特征出现的经济关系特点。这一问题虽然极具研究价值，但已远远超出了生物学研究的范围。\n

These changes are the result of both natural processes and human economic activity. Many natural processes proceed so slowly that in plain areas, what may have been of practical significance in recent centuries is only the century-old fluctuations in climate and their associated phenomena. Human economic activities, on the contrary, will cause rapid and profound changes in the geographical environment. However, many aspects of human influence on nature have not yet been fully clarified, and the practical significance of its activities is often underestimated or even completely ignored.\r\nThis book attempts to reveal the changes in vegetation cover and fauna in the clayey semi-desert area in the northwest of the Caspian Lowland over the past two centuries under the influence of human economic activities and century-long fluctuations in humidity. Particular attention is paid to by-product processes, which are major aspects of economic activity, because they are most often ignored. The book does not deal with the direct results of various economic activities, nor does it deal with the characteristics of the economic relationships that contribute to the emergence of anthropogenic features in the northwest of the Caspian Lowlands. Although this issue is of great research value, it goes far beyond the scope of biological research.\r\n
